In the view, I tried to insert a form:
#{form @Website.editPOST(page.id)} ... This failed with a
NullPointerException and no details:
Oops: NullPointerException
An unexpected error occured caused by exception
NullPointerException:

play.exceptions.UnexpectedException: Unexpected Error

Usually the Play! error messages are very detailed. Maybe this
case
could be added and an appropriate error message (e.g. "Missing
parameter 'id'") can be added.

I can't reproduce this either anymore. Strange. It took me a
while to hunt down the root cause for the above exception at the
time the problem happened. There must have been something else in
the mix (maybe with the routes configuration...).

I don't think it's worth spending more time on this since it's
not a critical issue. You can probably just close this ticket.

<h2>Play framework</h2>

Play makes it easier to build Web applications with Java. It is a clean alternative to bloated Enterprise Java stacks. It focuses on developer productivity and targets RESTful architectures. Learn more on the <a href="http://www.playframework.org">http://www.playframework.org</a> website.<br><br>

<h2>Source code is hosted on github</h2>Check out our repository at <a href="http://github.com/playframework/play">http://github.com/playframework/play</a><br><br>

<h2>Creating a bug report</h2> Bug reports are incredibly helpful, so take time to report bugs and request features in our ticket tracker. We’re always grateful for patches to Play’s code. Indeed, bug reports with attached patches will get fixed far quickly than those without any.<br><br>

Please include as much relevant information as possible including the exact framework version you're using and a code snippet that reproduces the problem.<br><br>

Don't have too much expectations. Unless the bug is really a serious "everything is broken" thing, you're creating a ticket to start a discussion. Having a patch (or a branch on Github we can pull from) is better, but then again we'll only pull high quality branches that make sense to be in the core of Play.
